Mono-base & Stand-alone Slip Tables

edition: January 2019

Mono-base and Stand-alone Slip TablesWith today’s demanding test requirements there is an increasing need for slip tables to facilitate testing in a horizontal position. 1g Dynamics offers mono-base and stand-alone slip tables available with low, medium and high-pressure hydrostatic guidance bearings in standard sizes ranging from 300 mm (12 in) to 2500 mm (98 in). Virtually any size of slip table can be produced to suite the customer’s required over-turning moment in the Pitch and Roll directions and Yaw axis when testing large payloads with an offset centre of gravity.

In a mono-base configuration the vibrator and slip table share a structural steel body that enables rapid conversion between vertical and horizontal positions and the accurate alignment of the vibrator relative to the slip table when rotated to the horizontal position.

In a stand-alone configuration an independent steel platform supported by leveling feet allows any vertical vibrator from

1g Dynamics or other manufacturer to couple with the slip table assembly.

LPT Series Low Pressure Slip Tables 300 to 1200 mm (11.8 to 47.25 in)

LPT Series oil film tables are designed for general-purpose horizontal testing of small and medium sized products with a low centre of gravity. Oil is supplied through portholes in the granite base and is dispersed throughout the underside of the slip plate. The oil film provides a low friction surface, a damping medium for restraint of resonances, pitch and roll moments. Yaw restraint is provided by the V-groove guide bearings combined with the armature guidance system.

LPT Series guide bearings are primarily designed for use with 1g Dynamics mono-base vibrators but are available as a stand-alone slip table for any existing or new vibration test system.

◆ Light weight magnesium slip plate

◆ Integral hydraulic pump, reservoir and filter

◆ Yaw restraint provided by V-groove guide bearings combined with the armature guidance system

◆ Less expensive technique to perform horizontal testing

T-Series Medium Pressure Slip Tables 800 to 2500 mm (27.5 to 98 in)

The T-Series slip table systems from 1g Dynamics are based upon modular T-film hydrostatic bearing elements operating at 600-psi oil pressure. Each element measuring 300 x 300mm (12 x 12in) is designed to support a slip table of the same size, exactly as a granite slip surface which the bearing elements replace. Virtually any size of slip table can be produced to suite the customer’s required over-turning moment in the Pitch and Roll directions. Special bearings are available to provide extra restraint in the Yaw axis when testing heavy asymmetric payloads with high centres of gravity.

The T-Series Slip Tables are available with any mono-base shaker and as a stand-alone product for any existing single and multi-shaker installation.

◆ Extraordinary payload capability

◆ Excellent control of vertical cross-axis motion

◆ Outstanding dynamic stiffness and transmissibility

◆ Adaptable to suite customer’s required over-turning moment

◆ Lower maintenance costs over an extended period of time

HBT Series High Pressure Slip Tables 600 to 1800 mm (23.6 to 71 in)

The HBT Series design provides a high over-turning moment and cross-axial restraint. This concept combines a standard slip table assembly with 3,000-psi hydrostatic bearings to provide high dynamic moment restraint while preserving the damping characteristics of an oil film. This system allows testing of tall and heavy products with high centers gravity by reacting moments through the hydrostatic bearings. Cross-axis motion is constrained and is typically less than 10% of input at frequencies up to 2000 Hz. except at resonance. Additional hydrostatic bearings can be supplied to provide extra restraint when testing parameters require a higher overturning moment.

The HBT Series Slip Tables can be configured to any size or shape and are available with any mono-base shaker and as a stand-alone product for any existing single and multi-shaker installation.

◆ High dynamic moment restraint

◆ Hydrostatic bearings restrain high Pitch, Roll and Yaw moments

◆ Light weight magnesium slip plate
